This preview for what to expect on next week’s Jersey Shore (Season 5, Episode 8, according to PerezHilton) is jam-packed with series-changing events, starting with The Situation’s decision to finally stop talking his talk and start walking his walk. He tells Jionni the “truth” about his and Snooki’s alleged hook-up when Jionni and Snooks’ relationship was still brand-new.

Also: Former castmate Angelina is back! Pauly D and Vinny spot her at Jenk’s and give her an obligatory kiss on her heavily made-up cheek, before Pauly D tries to avoid her at all costs, and Vinny ponders taking her home and “banging her.” Will she stay or will she go now?

Deena Nicole goes for a midnight dip, fully-clothed, in the sparkling Seaside Heights ocean, only to be interrupted by the cops. And it looks like Snooki will be back to her old throwing-everything-in-sight-at-Mike ways, only this time with milk. Enjoy!
